Method UseError

core/router/api_builder.go:1294–1296

UseError upserts one or more handlers that will be fired, as middleware, before any error handler registered through `On(Any)ErrorCode`. See `OnErrorCode` too.

(handlers ...context.Handler)

// as middleware, before any error handler registered through `On(Any)ErrorCode`.
// See `OnErrorCode` too.
func (api *APIBuilder) UseError(handlers ...context.Handler) {
	api.middlewareErrorCode = context.UpsertHandlers(api.middlewareErrorCode, handlers)
}

// Use appends Handler(s) to the current Party's routes and child routes.
// If the current Party is the root, then it registers the middleware to all child Parties' routes too.
